On thearbor Dis Be it known that I, FRANK T.

This device holds the wheel I-I against rotation, but permitsthe lever L to still move and operate the hand Gr.

It is important to have combined with the pressure-gage which indicatesthe depth of submergence of the boat another gage to indicate theinclination in degrees with the level of the water of flotation of thelongitudinal axis of the boat or vessel, and such a gage is provided bythe present invention. This device will now be described.

On the dial B and occupying a slot therein is a curved tube P, of glass,containing a suitable liquid, such as is commonly found inspirit-levels. This tube is marked with grad uations z, and the bubbleZ) in the tube indicates the degree of inclination of the boats axis.The-gage should be set in the ,center of the longitudinal oscillation ofthe boat.

Obi'iously the relation or proportion between the scales .2 and y neednot be that herein shown; but it is convenient to have one indicatingmeans on a scale three times that of the other. It is also convenient tohave the two scales of circular form and parallel, as shown; but thescales are practically one so far as the graduations are concerned,being distinguished mainly by the scale-numerals.

The dial B will be by preference a full plate; but this is notimportant, so long as it is capable of performing its functions.

Having thus described my invention, I

claim- 1. A pressure-gage having two indicating devices, one, forindicating lower pressures, having a plainer and more easily read scale,and the other, for indicating the higher pressures, having a finerscale, means in common for operating the hands of the said indicatingdevices and moving them at different rates of speed proportioned to thescales, and means for arresting the more rapidly moving hand at apredetermined point without arresting the other hand.

2. A pressure-gage with two indicating devices, said devices havingparallel scales of substantially equal length, one for indicating thelower pressures and the other the higher pressures, hands which traversethe respective scales, gearing which moves said hands over the scales atdifferent rates of speed, means, in common with both hands, foroperating said gearing, and means for arresting the more rapidly movinghand when it shall have reached the end of its scale.

3. A pressure gage with two indicating mechanisms each having a hand anda scale traversed thereby, means in common for moving said hands, saidmeans moving one hand a greater distance than the other in a giventime,and said scales having their scale-numerals spaced in proportion,respectively, to the speed of the hands traversing the scales, and meansfor arresting the more rapidly moving hand at a predetermined pointwithout arresting the other hand.

4:. A pressure-gage comprising a casing, a dial having on it the twoscales as and y, a central arbor D, a handE carried by said arbor, asleeve F rotative on said arbor, a hand G carried by said sleeve, saidhands traversing the respective scales :1; and 3 a rocking lever Lcarrying racks J and K, the said racks, wheels H and I, of differentdiameters carried by the respective arbor D and sleeve F, and gearingwith the respective racks J and K, and means for turning said lever Labout its fulcrum, whereby the hands are moved at different rates ofspeed.

5. A pressure-gage comprising a casing, a dial having on it, two scalesat and y, a central arbor D, a hand E carried by said arbor, a sleeve Frotative on said arbor, a hand G carried by said sleeve, said handstraversing the respective scales, a rocking lever L, a full rack K,carried by said lever, a rack J which has a toothless portion J, carriedby said lever, the wheel I, carried by the sleeve F and gearing with therack K, the wheel II on the arbor D and gearing with the rack J, saidwheel having an untoothcd portion II adapted to bear on the smoothportion of the rack, and means for turning said lever L about itsfulcrum, substantially as and for the purpose set forth.

6. The combination with a depth-gage hav ing a dial with scales andmeans for moving hands over the respective scales, of aninclinatioirgage comprising a curved and graduated tube set in andcarried by the dial of the pressuregage and containing a liquid andbubble which traverses the graduations on the tube.

In witness whereof I have hereunto signed my name, this 1st day ofNovember, 1902, in the presence of two subscribing witnesses.
